T 0 all whom may concern.

lie it known that l, lVnnNnn I. STAAF, a resident of Pittsburgh, in thecounty 0t Allegheny and State of Pennsylvania, hays invented a new anduseful Improvement in Liquid-Meters, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part which Figure l is an end elevation, partly brokenaway, of-a meter embodying my invention; Fig. 2 is a side view, alsopartially broken away; and Fig. 5 is a sectional view of a portion ofthe meter.

My invention has relation to liquid ineters, and is designed to providea meter of simple and eficient character which will measure either theweight or volume of the liquid passing therethrough, and which also hasmeans for recording and indicating the temperature of the water.

The nature of my invention will be best understood by reference to. theaccompanying drawings, in which I have shown my preferred embodimentthereof, which will now be described, it being premised, however, thatvarious changes may be made in the details of construction andarrangement of the parts, without departing from the spirit and scope ofmy invention as defined in the appended claims. y

In these drawings, the numeral 2 designotes a cylinder, having an inletconnection 3 and an outlet connection 4:, tor the liquid to be measured.These connections are at the lower portion of the cylinder at oppositesides; but the inlet orifice 5 is well up toward the horizontal centerline of the cylinder, the upper edge of the orifice being preferably ator near such horizontal center line. The outlet orifice 6 also has itsupper edge preferably extended up, to the hori- Zontal center line ofthe cylinder, and its Specification of Letters Patent.

shown at the. right-hand side of Fig. 3, they form relatively deepbucket-s, with upwardly extending, outwardly directed, outer end walls.or flanges. As this flange of each bucket uncovers the upper edge of theinlet orifice 5, a portion of the entering water or a suitable gearWheel 9, which meshes with another gear wheel 10, the latter driving aflexible shat't 11, which is connected up to and drives a suitableregister 12. This register is of any well known form, and may be made toindicate either weight or volume of Rising from the cylinder 2' is apost or column 13, upon which. is mounted a case 14:, containing arecording thermometer 1-5. This thermometer may be off any well knowncharacter, and may be driven by clock work, or in any usual way.

' 16 is the thermometric element, which actuates the pencil of therecording thermometer, and which is carried downwardly and into theoutlet connection 4 of the meter so as tobe affected y the temperatureof the outgoing water;

My invention provides an extremely simple and convenient form of meter,by means of which either the weight or volume of water, or other liquidmay be registered, and which will also make a continuous record of thetemperature of the water.

What I claim is l-- I 1,. A. liquid meter, comprising a cylinder havingan inlet opening at one side and an outlet opening'at the opposite side,a horizontal shalt journaled in said cylinder and extending through oneend thereof, blades or buckets carried by the shaft within the cylinder,a vertical column mounted on said cylinder, a meter device supported bysaid column, gear connections between the movable elements of the meterand the extended end of said shaft, a thermoinetric element extendinginto the path of flow through said cylinder, and a. recordingthermometer 1nstrulnent also mounted on said column, and having anactuating connection with said tllOl'lllOlllGlZl'lC element;substantially as described.

2. A liquid meter, comprising a cylindrical casing, a shaft extendingtherethrough, a series of bucketshaped blades fixedly connected to saidshaft, each of said blades having an outer Wall which extends in an up--Ward and outward direction when the blade is at the down-going side ofthe meter, the casing having lateral inlet and outlet openings atopposite sides thereof, at points nearly at the horizontal center lineof the shaft, the upper edge of the inlet opening being at a point nearthe horizontal center line of the shaftand said opening being wider thanthe adjacent edge of a blade so that liquid will be discharged into thecasing above and also below each blade when the latter is adjacent tothe center line of the opening; substantially as described.

3. A liquid meter, comprising a cylindrical casing, a shaft extendingtherethrough, a series of bucket-shaped blades fixedly connected to saidshaft, each of said blades having an outer wall which extends in anupward and outward direction when the blade is at the down-going side ofthe meter, the casing having lateral inlet and outlet openings atopposite sides thereof and at points nearly at the horizontal line ofthe shaft, the upper edge of the inlet opening being at a point near thehorizontal center line of the shaft, said opening being wider than theadjacent edge of a blade so that liquid will be discharged into thecasing above and also below each blade when the latter is adjacent tothe center line of the opening, and the edges of the blades contactingwith the inner wall of the casing throughout their travel between theedges of the inlet and the outlet openings; substantially as described.

In testimony whereof, l have hereunto set my hand.
